    No, because then the stylesheet would be controlling behavior in 
addition to presentation. Should changing the stylesheet or switching to 
no style (as in Firefox) affect whether or not form controls are 
successful? I don't see a use case for that, and even if there was one, 
XBL could cover it.

    In any event, the name of the property is "display", so if it can 
affect form control submission, it's poorly labeled.

    Near as I can determine, this value is proprietary or never existed 
in the first place. It does not exist in the CSS1, CSS2, CSS 2.1 or CSS3 
Box Model specifications. From searching the web, it would appear that 
the "hidden" value originates from a typo in a WCAG 2.0 working draft:

http://lists.w3.org/Archives/Public/public-comments-wcag20/2004Dec/0020.html

    In this case, the text should have probably said "visibility: 
hidden" instead of "display: hidden". Since a "hidden" value for display 
would likely lead to suggested values like "hidden-inline" or 
"hidden-table-cell", it hardly seems logical anyways.
